Introduction to Overmold
Overmolding is a manufacturing process that involves molding one material over another. This technique is widely used in various industries to combine the best properties of different materials, such as hardness and flexibility, or to enhance the aesthetic and functional aspects of a product. In overmolding, a base material (usually a rigid plastic) is first molded, and then a second material (often a softer elastomer) is molded over the first one. This can create products with improved grip, comfort, durability, and a more appealing appearance. Overmolding is commonly applied in automotive parts, consumer electronics, medical devices, and many other fields.
